CAR-DOOR LOCK.

Application filed January 10, 1922. Serial No. 528,245.

To all whom it may concern:

Be it known that I, WILLIAM E. WINE, a citizen of the United States ofAmerica, residing at Toledo, in the county of Lucas and State ofOhio,have invented certain new and useful Improvements in Car-DoorLocks, of whichthe following is a specification.

My invention relates to new and usefu improvements in car door lockingmeans, and more particularly to locks that are adapted to support-andretain the doors of a hopper car in their closed position.

One of the objects of the present invention is to provide. a lockingdevice that is exceedingly simple in construction, readily assembled,cheap tomanutacture and easily and readily secured tothe car doors.

As is well known to those skilled in the art, the hoppers in a car areangularly disposed with relation to the car floor and the doors areswung'from a point at the top of the sides of the hopper.

The present invention contemplates a hook secured to the outside of thehopper while the lock comprises a body plate on which is a latch anddog, the plate to. be secured to the lower end of the door and at theside thereof. Although only one hook and one look is shown in thedrawings, it will, of course, be understood that a similar hook andlatch will be supplied for the other side of the hopper and door so thatthe door will be retained and locked from its opposite outer corners.

With these and other. objects in view, the invention consists in certainnew and novel arrangements 7 and combinations of parts as willbehereinafter more fully described and pointed out in the claims.

Referring now t the drawings showing a preferred form of my invention:

Fig. 1 is a fragmentary view of the side of a hopper showing the hookfastened thereon, the lock secured to the hopper door, a fragmentaryportion of the door being shown andin its closed position.

Fig. 2 is a sectional view taken on line 2 2 of Fig. 1 lookinginthedirection of the arrow, and

Fig. 3 is a bottom plan View of the lock secured to the bottom of thedoor.

Referring now to the several figures, a;

fragmentary portion 1 of the side plate of a hopper is shown togetherwith an outer flange 2 on a hopper door 3. The hinge point of the door 3is not shown, butfit will be understood that it is at a point near thetop of the hopper. Securely rivet- Securely riveted to the bottom of thedoor.

3 and directly behind the flange 2 is the triangular bracket plate 7which is provided with the integral bosses or posts 8, 9, and

'10 which bosses all extend beyond the 0pposite sides of the plates andare each drilled as at 11 for the reception of rivets 12.

The portions otthe. bosses 8, 9 and 10 on the side of the plate formlegs which rest on the bottom of the door 3 through which the, rivets 12are passed so that the plate 7 will extend in a plane below that of theouter edge of the flange '2. Theportion of the bosses 8 and 10whichextend from the opposite side of the plate 7 form bearings for thereception of a pivotal latch 13 and a dog 14-, the lower boss 9 at thisside of the plate and the upper boss 8 having a strap 15 riveted to themto retain the dog 14. and hold the latch .13 from lateral movement,while the downward movement of the'latch 13 will be limited by by theboss 9 as may be clearly seen in Fig. 3. I

The location of the. casting 4L with relation to the plate 7 is suchthat when the door is closed and the latch" 13 is in its locked positionas shown in the different figures, it will rest on the ledge 6 of thehook and cannot be lifted or removed from this position until the dog 14is swung rearwardly, whichmay be done by striking the outwardlyextending lug 16 of the door with a hammer or other instrument.

The casting 4. as well as the plate and latch 13 may be slightly coredor'ribbed as shown in the several figures to provide sufficient strengthfor these members, as these locking devices, as a whole, must berelatively strong as the doors and the load are comparatively heavyones.

. h sh p o t e erouter edg o th hook 5 is such that it will raise thelatch as the door is swung to its closed position so that the latch willdrop into place on the ledge when the door is in its final or closedposition. In other words, the latch will drop in place on the closing fthe door and will there be further securely held in place by the jammingof the dog into position.

From the foregoing it will be seenthat the door may be provided with theoutwardly extending flange 2 which will strengthen the door'and alsoshelter the bosses or posts on ithe plate 7 from injury, while at thesame time, the flange does not otter any obstruction to the lockingdevice as these bosses are of sufficient length to hold the look beyondthe lower edge of the flange.

It will also be seen that l; have provided a lock which is extremelysimple, that will dropinto place when the .door is .closed and on theother hand cannot become accidentally disengaged in. use.

Although I have shown the locking device in conjunction with a hopperdoor, it will be understood that the device might well be used withdrop. bottom doors on cars of other types.

Many slight changes .may .be made without in any way departing from thespirit and scope of the invention.

What I claimas new and desire to secure by Letters Patent is:

l. A car. door locking device comprising a body plate, having post-sformed thereon, said posts extending beyond the opposite Sides of saidplate, and said posts being drilled, a latch pivotally secured to one ofsaid posts, a dog pivotally secured toanother of said posts, and thelowermost post forming a lower limit of movement for said latch. r

2. A car door locking device comprising a body plate. threepostsarranged about and extending transversely on each side of said bodyplate, the portions of the posts on one side of the plate forming legs,adapted to be secured to a door, a dog pivotally secured to one postonthe opposite side of said plate and a :latch pivotally secured beneathsaiddog to another of said posts, the lowermost poston this side of theplate forming a limit for the downward movementof said latch. I

,3. In combination with a hopper and doo having an outwardly extendingflange there- ,on, a hook secured to theside of the hopper, a body platesecured to the bottom of the door, integral legs formed onone side ofidplate, and oppositely disposed bosses a strap connected with thelowermost boss and the boss forming a pivotal point for said dog, andsaid latch co-operating with said hook when the latch is in its lowerposition to retain the door in its locked and closed position.

4. In combination with a hopper and door, a hook secured to theside ofsaid .hopper, a body plate, posts extending through said body plate andthe portion of said posts on one side of {the plate forming legs to besecured to the door, and the portions of the posts on the opposite sideof the plate rorming espectively pivotal posts and a stop, a latchsecured to one pivotal post anda dog mounted on the other of saidpivotal posts,.a strap connecting the pivotal post of the dog and thestop tov retain the dog and latch member on said posts, said latchmember resting on said hook and held against movement when the door isin ,its closed position and said dogforming. an auxiliary locking meansfor said latch.

5. A car door locking device including in combination with aswingingdoor having an out-turned flange formed along ,one
